2 Thessalonians 2:15

He deduces this exhortation on good grounds from what goes before, inasmuch as our steadfastness and power of perseverance rest on nothing else than assurance of divine grace. When, however, God calls us to salvation, stretching forth, as it were, his hand to us; when Christ, by the doctrine of the gospel, presents himself to us to be enjoyed; when the Spirit is given us as a seal and earnest of eternal life, though the heaven should fall, we must, nevertheless, not become disheartened. Paul, accordingly, would have the Thessalonians stand, not merely when others continue to stand, but with a more settled stability; so that, on seeing almost all turning aside from the faith, and all things full of confusion, they will, nevertheless, retain their footing. And assuredly the calling of God ought to fortify us against all occasions of offense in such a manner, that not even the entire ruin of the world shall shake, much less overthrow, our stability.

15Hold fast the institutions. Some restrict this to precepts of external polity; but this does not please me, for he points out the manner of standing firm. Now, to be furnished with invincible strength is a much higher thing than external discipline. Hence, in my opinion, he includes all doctrine under this term, as though he had said that they have ground on which they may stand firm, provided they persevere in sound doctrine, according as they had been instructed by him. I do not deny that the term παραδόσεις is fitly applied to the ordinances which are appointed by the Churches, with a view to the promoting of peace and the maintaining of order, and I admit that it is taken in this sense when human traditions are treated of, (Matthew 15:6.) Paul, however, will be found in the next chapter making use of the term tradition, as meaning the rule that he had laid down, and the very signification of the term is general. The context, however, as I have said, requires that it be taken here to mean the whole of that doctrine in which they had been instructed. For the matter treated of is the most important of all — that their faith may remain secure in the midst of a dreadful agitation of the Church.

Papists, however, act a foolish part in gathering from this that their traditions ought to be observed. They reason, indeed, in this manner — that if it was allowable for Paul to enjoin traditions, it was allowable also for other teachers; and that, if it was a pious thing (691) to observe the former, the latter also ought not less to be observed. Granting them, however, that Paul speaks of precepts belonging to the external government of the Church, I say that they were, nevertheless, not contrived by him, but divinely communicated. For he declares elsewhere, (1 Corinthians 7:35,) that it was not his intention to ensnare consciences, as it was not lawful, either for himself, or for all the Apostles together. They act a still more ridiculous part in making it their aim to pass off, under this, the abominable sink of their own superstitions, as though they were the traditions of Paul. But farewell to these trifles, when we are in possession of Paul’s true meaning. And we may judge in part from this Epistle what traditions he here recommends, for he says — whether by word, that is, discourse, or by epistle. Now, what do these Epistles contain but pure doctrine, which overturns to the very foundation the whole of the Papacy, and every invention that is at variance with the simplicity of the Gospel?
